Hi @howard.tobin,
We’ll need a little more information to take effective troubleshooting action on this report.
Are you having trouble launching Roon while the server is active in the menu bar? Or did the GUI fail to install at all?
Our diagnostics servers indicate that you have a RoonServer instance active on a machine and OS matching the description from your post. There doesn’t appear to be a matching GUI installed, however.
The most immediate solution would be to delete the GUI, keeping RoonServer (your database) installed. This is more complex than simply deleted the app from MacOS - please follow the steps below closely.
- Exit out of Roon
- Navigate to your Roon [Database Location]( https://kb.roonlabs.com/Database_Location )
- Find the folder that says “Roon”
- Rename the “Roon” folder to “Roon_old”
- Reinstall the Roon App from our [Downloads Page]( https://roonlabs.com/downloads ) to generate a new Roon folder
- Connect to the existing RoonServer on your MacOS instance.
